High-voltage, high-current power for your custom electronics.
This EVE 25P 4S 18650 Battery Pack features four genuine EVE 18650-25P high-rate cells connected in series (4S) in a compact linear layout. It delivers a nominal 14.8V voltage (16.8V full charge) and a solid 2500mAh capacity.
The integrated Protection Board (BMS) is the key feature of this pack, offering comprehensive safety against overcharge (cut-off at 16.8V), over-discharge, over-current, and short circuits. Unlike smaller 6A limited packs, this battery supports a 10A continuous working current (with a 20A peak for instant startups), making it much more versatile for 16V power tools, robotics, and high-power DIY electronics.
Pre-wired with a default XH2.54 2-pin connector (red/black), it is ready to plug into your custom 14.8V/16V systems.
Key Features
4S Series Configuration (14.8V / 16.8V): Provides a high 14.8V nominal voltage (16.8V full charge) for devices requiring a 16V power source.
High Current Output (10A Continuous): Supports up to 10A continuous discharge and 20A instantaneous peak, making it suitable for moderate-power tools and high-demand devices.
Built-in Protection Board (BMS): Features overcharge protection (16.8V cutoff), over-discharge, over-current, and short-circuit protection for safe operation.
Genuine EVE 25P Cells: Authentic high-rate 18650 cells ensure reliable 2500mAh capacity and long cycle life.
Pre-wired & Plug-and-Play: Comes with a default XH2.54 2-pin connector (red/black leads, 8-15cm) for easy integration.
Compact Linear Layout: Shrink-wrapped with the side protection board, measuring approx. 75mm (L) x 70mm (W) x 18.5mm (D).
Parameters
*Dimensions are approximate and include the protection board and heat shrink wrap. Please allow ±1-2mm tolerance.
Applications
Recommended For:
DIY Electronics & 16V Devices: Perfect for custom 16V audio amplifiers, portable speakers, and electronic circuits.
Moderate-Power Power Tools: Suitable for small electric drills, screwdrivers, and tools that draw up to 10A.
Robotics & Custom Projects: Reliable 14.8V power for motors and controllers drawing within the 10A limit.
LED Lighting: Suitable for high-power 12V/16V LED strips or work lights (under 10A).
Not Recommended For:
High-Drain Power Tools or Heavy RC Models (>10A): Do not use in heavy-duty drills, saws, or large RC cars that draw 20A+ continuously. The 10A limit will trip the protection board under heavy loads.
Devices Requiring Bare Cells: If your device's battery tray expects a standard flat-top cell, this pre-wired pack will not fit.
12V Devices without Voltage Tolerance: While 14.8V is often used as a "16V" replacement, ensure your 12V device can handle up to 16.8V before using.
FAQ
Q1: What does "4S" mean and how does it differ from a single cell?
A: "4S" means 4 cells in Series. This increases the voltage to 14.8V (16.8V full charge) while keeping the capacity at 2500mAh.
Q2: What is the maximum discharge current?
A: The built-in protection board allows a continuous working current of up to 10A, with an instantaneous peak of 20A. This makes it more powerful than standard 6A-limited packs.
Q3: How do I charge this 14.8V pack?
A: You must use a dedicated 4S Li-ion charger (16.8V output) or integrate it into a custom charging circuit with the correct 16.8V cutoff. The recommended charging current is 1A-3A.
Q4: Can I use this for my power tool?
A: It depends on the tool. If your tool draws less than 10A continuous, it will work. For high-drain tools (15A-30A+), you need a pack with a higher-rated BMS or unprotected bare cells.
Q5: What is the connector type?
A: It comes pre-wired with a default XH2.54 2-pin connector (red/black). Other connector types may be available upon request.
